Application died December 6, 1884. Serial 110. 581,081.

I citizen of the United States, residing m Somerville, in the county ofMiddlesex and State of Massachusetts, have invented a new and ImprovedLasting-Machine, of which the following specification and accompanyingdrawings are such a full, clear, and exact description as will enablethose skilled in the art to make and use the same.

The present invention relates to lasting machines, and more particularlyto that typeof lasting machines in which the upper 15 secured to theinner sole by stitching it thereto.

The object of the invention is to reorganize and improve lastingmachines in the respects hereinafter pointed out, and to thiseud theinvention consists in the devices and combinations of deviceshereinafter described and claimed.'

Hcretofore in machine lasting of boots and shoes, the inner soles anduppers have been asembled upon the lasts and there socured in positionwith several tacks before thev were presented to the machine, afterwhich the uppers were drawn around-the lasts and secured to the innersoles by a series of operations partly manual, and partly mechanical.

in the present machine, the uppers, lasts and iunersoles are assembledin a jack which has means to clamp the'upper at the ends of the last andconform it thereto and which holds the upper and last in position, withthe edges of the upper substantially perpendicular to the face of theinnersole, and the jack is then presented with the unlasted shoe thereonto mechanism which automaticall cuts the margin of the upper seriallyinto sections, and then draws the sections over .1 on the insole andsecures them to the insole )y stitches.

The preferred form of the present invention is shown in. theaccompanying drawings in which, 7

Fig. 58 is a side elevation of the same parts and Fig. 59 isan end view showing the manner in which the wings are mounted on thestandards 23 and 24.

In the drawin 1 is the base of the machine from whic project thestandards 2 and 3 in which are suitable bearings 4 for the main shaft 5.Loosely mounted upon the main shaft? is a belt pulley A, located betweenthe standards 2 and 3, said pulley bein connected at times to said shaftby a suita le clutch mechanism under the control of the operator toactuate the machine as is usual in machines of this character. The jackis arranged to be moved vertically 1 to bring the edge of the upper of ashoe on a last placed on said jack in position to be acted upon by thedevices which pull over and secure the edge of the upper and is alsocaused to travel along beneath said devices to bring successive portionsof the edge of the a per in position to be acted upon by said evices.

To secure the above result the standard 2 has upon its sides suitable'des 6 in which are fitted for a vertical sliding movement the guiderods 7 upon the upper ends of which is mounted a table 8. e table 8 isnormally yieldingly sustained by suitable springs, such as the coiledsprings 9, whereby the jacked last and shoe is presented in propervertical position to be acted upon by the mechanism which pulls over andsecures the edge of the upper. As shown in the drawings thesprings arethree in number and bear against the under side of the table 8 at theirupper ends, their lower ends rest ing upon a cross-piece 46* of thestandard 2, The table 8 and the jack mounted thereon, may be de ressedagainst the force 0L springs 9, w en removing a lasted shoe andreplacing it with anunlasted shoe, and to hold it in its depressedposition I have rovided a counterweighted latch 10 whic is arranged toengage a notch 11 formed in one of the guide rods 7 as clearly shown inFi 2. v e

The jack is preferably constructed and arranged as shown in Figs.1,.2,9, 10 and 11. 57, 58 and 59 and comprises a base plate 12 having a airof upwardl projecting ribs 13, upon t e upper edges 0 which is a plate14, provided with ribs 15, the inner faces of which form a dovetailguideway 15* which extends along the longitudinal center of the late 14for nearly-the length of said plate.

itted to slide alon this guide way 15* are suitable blocks 16, 1% and18'upon which are carried the heel and toe clam s and the jack post andtoe rest, as will be ereinafter described. The heel and toe clamps 19and 20 are preferably thin blades or plates which approximately conformto the ends ofthe last at the toe and heel and are each provided with aflange at their lower parts by which they are removably' secured in anysuitable manner to ,the pivoted wings 21, and they are so fixed upon thewings 21 that their central point of contact is coincident with thecenter of motion of said wings. The clamps 19 and 20 are changed forvariations of style of toe or heel, but not for variations of length oflasts of the same style. The wings 21 as shown in Figs. 57, '58 and 59are rovided with shanks 21 integral with co lars 21 by which the arepivotally mounted on pivots 22 whic are fixed in the standards 23 and 24projected vertically from the slide blocks 16 and 18. Projecting fromthe bearings of the wings 21, are the arms 25, the inner sides of whichare inclined from each other and havin rounded ends, the arrangementbeing suc that a suitable device may be forced between the arms 25forcing them apart and causing the wings 21 to turn on the pivots 22 toclose the clamps 19 and 20 upon the ends of the last firmly clam in theupper and conformin it to the en s o the last.

e mechanism for actuating the clamps, is of the following constructionand arrangement: Fixed to the top oi plate 14 are the stands 26 providedwith suitable bearings in which are mounted to turn, but fixed fromlongitudinal movement therein, the right and left screws 27. The screws27 are geared together as shown in Figs. 1 and 9 to turn in unison andare provided with means such as a square taper spindle, to be engagedand actuated by a crank; These screws 27 engage nuts 28 which arepivoted provided with pins 29 which are received in correspondinglyshaped holes in said swinging levers, which are pivoted at 31 to theslide blocks 16 and 18 so that a rotation of the screws will swinglevers 30' in the blocks 16 and 18. The lower ends of the levers 30 arefitted in suitable bearin s 30* in the blocks 16 and 18 the walls 0 saidbearings acting as stops to limit the swingin mm tion of levers 30 inboth directionsftfie result being that when said levers have reached thelimit of their throw in either direction, a further rotation of thescrews 27 will cause the blocks 16 and 18 to move along the guide way15* toward or away from each other; Fixed to the u per ends of thelevers 30 are the rounded pins; or bearings 32 upon which are looselymounted the rolls 33, the central holes in which are preferably largerthan the hearings or pins 32 allowing considerable lost motion of therolls 33 so that the rolls 33 may assumean eccentric position when theclamps are act ing upon crooked lasts in order that said clam s mayconform thereto. The above described mechanism is such that when thescrews 27 are actuated to draw the levers 30 toward each other, therolls 33 upon the upper ends of said levers engage between the arms 25of the clamps 19 and 20 force the arms 25 apart, and close the clamps 19and 20 around the ends of the last, the lay of the rolls 33 upon theirbearings allowing the clamps 19 and 20 to automatically adjustthemselvcs to lasts which have considerable swing or lateral inclinationof the toe, or to right and left lasts, as the case mi ht be.

11 order that the clamps 19 and '20 may remain open during the movementof the slide blocks 16 and 18 toward and away from the last and untilthey have reached the ends of the last, 1 have arranged suitable springs34 in seats or pockets 34 in the upper ends of the standards 23 and 24,the-outer ends of said springs 34" engaging the upper ends of the levers30 tending normally to force said levers 30 away from the standards 23and 24, the backward movement of the levers 30 being so limited bycontact with the ends of the slots 30" that when forced back to theirfull; extent, the clamps 19 and 20 may be opened to receive the largestlast of the series they are designed to operate upon. When theblocks 16and 18 have brought the clamps into contact with the ends of the last, afurther rotation of the screws 27 will swing the levers 30 inwardagainst the pressure of springs 34", causing the rolls 33 to engage thearms 25 and close the clamps around the last. The centers of the clampsare fixed with relation to the longitudinal center line of the to theswinging levers 30, said nuts being base plate, and they always bringthe centers of the toe and heel of the last coincident therewith,regardless of the longitudinal swing of the-last. Upon a slidin block 17placed between the blocks 16 an 18 is a stand 34 upon one end of whichis arranged the toe rest 35 said toe rest bein arranged to slide thereonfor lon 'tudina adjustment, and upon the other en of said stand 34 isarranged the jack post and pin 36 which is adapted to swmg laterallyupon a pivot 36* for a transverse adjustment. The stand 34 has a basewhich is secured to the block 17; from the base the body of the standrises vertically, carrying a for-- wardly projected bar whlch isembraced by the base of the toe rest 35 (see Figs; 11 an 9) upon whichprojection the toe rest ma be Slld to the proper position, and'upon therear side of the body of the stand the jack post and pin 36 is securedby means of the pivot 36* above referred to.

The slide blocks 16, 17 and 18 are allfitted to more freely along theguideway 15*, and to maintain the blocks in proper position relative toeach other I have provided the springs 37 and 38 which are fitted inbearings 38* in the blocks 16, 17 and 18. The

relative'compressibility of the springs 37 and 38 is preferably suchthat as the 0 amps 19 and 20 are moved by the screws 27 toward the lastupon the jack pin the heel clamp will come into contact with the lastfirst, causing the toe of the last to be forced down against the toerest, whereby the upper will be first clam ed upon thel'ast at the heeland can then e pulled u and adjusted at the toe prior to the furt ermovement of the clamps to cause the toe clamp to engage the upper on thelast to hold the upper at the heeland toe in proper position without theuse of tacks.

In the operation of assembling and jacking, the last is placed insidethe upper and placed upon the jack pin, the screws 27 being turned untilthe center of the heel clamp l9.en'gages the center of the upper at theheel of the last which causes the toe of the last to be thrown down uponthe toe rest. The innersole is now placed upon the last, or theoutersole in the case of lastin' turns and the counters andquarters 0theupper correctly adjusted, whereu on the screws 27 are further turnedcausing the heel clamp 19 to be closed somewhat around the heel end ofthe last, and the center of the heel and toe clamps l9 and 20 to firmlyclamp the heel and toe of the upper against the last, the last becomingas it were an in nor clamping member and the clamps 19 and :30 an outerclamping member to hold the upper and insole in position durin thesubsequent operation of the machine t ereare caused to hold the up erwith its freeedge projected substantial y perpendicular to the face ofthe sole in proper position to be acted upon by the lasting devices.

The range of lengths of lasts is considerable and there are lar evariations of styles of heels andtoes an :1 Ion last will require morestitches to last t e upper than a short'one, and a large heel or toemore than a small one, and also the stitches should be spaced closer atthe heel and toe than along the sides. In the machine of the drawing, Ihavefprovided a jack feeding mechanism which willautomatically adaptitself to the re uirements of the particular size and style 0 last andwhen once set correctly for a particular. styleof heel and toe,

the act of jacking the last causes the autospace between them being ofsuch width relativel to the diameter of the pinionAO that sai pinionwill not engage with either rack 39, .when centrally betweenthem asshown in Fig. 10. The inion 40 is fixed to the upper end of a shat 41,which isfitted to revolve in a bearing 42 formed in the jacksupportingtable 8, so that said-shaft will rise and fall with saidtable. Shaft 41 is also fitted to revolve in and slide'vertically in, abearing 43 formed at the top of the jack'supporting standard 2, and toslide vertically in and revolve with the sleeve 4A which carries aratchet wheel 45 andjrevolves in bearings 46 in the standard 2. Thepinion 40 is given a step by steprevolution by a pawl 47, carried bytheupper end-ofa lever 48 each step representing one stitch ofthesewing' mechanism. The lower end of the lever 48 is formed into a cam49 which the cam roll 50 of the crank 51 fixed on the main shaft 5,engages, and swings at the correct times. The spring 52 rwses the pawl47 toward the teethofj e ratchet wheel 45 and theretainer pawl 53 andthe adjustable brake 54 insures the position of the pinion 40 when thesewing mechanism is operating, see Fig. 31. The pawl 47 is a block whichslides in a bearing in the upper end of the lever 48 and is pressedtoward the ratchet wheel 45 by the spring 52. The retaining pawl 53 isivoted to a stud 53' secured to the side 0 standard 2 and has aportion-acted upon by a spring 53",

oted to a stud 54 upon the side of standard formed upon the ratchet Thepressure of the brake shoe 54" may be adjusted to any desired degree bymeans of a screw .54 which is tapped into the wall of standard 2, theend of which engages the outer end of the brake lever 54. In the baseplate 12 of the jack is formed a slot 55 through which projects theshaft 41 and thus.the jack is enabled to move along past'said shaftduring its feeding movement. The slot 55 is wide enough to permit alateral movement of the jack to permit either of the racks 39 to engagethe pinion 40 but not wide enough to ermit the teeth of the pinion andracks to ottom, so that when the jack is swinging to adjust itself tothe lateral curvature of the bottom of the last alon the sides thereof,it will swing upon a bearmg'formed by the contact of the sides of theslot 55 and the shaft 41, instead of u on a bearing formed by the topsof the teetii of the racks 39, contacting with the bottoms of the spacesbetween the teeth of the pinion 40, thus reducing the friction ofswinging toa minimum.

In many types of boot and shormachinery such as pegging machines andsole cutting machines, t e acks were designed to be fed along by racksand pinions, but the racks in such machines were provided with curvedends or toothed segments at the ends, whereby the jack was turned as thework progressed around the toe or heel of the shoe. In suchconstructions the turning at the ends always required the same number ofmove ments of the feed mechanism and if the length of feed wereadjustable, such adjustment could only be obtained by a tooth by toothadjustment. It is recognized that the thickness of material in a shoe atthe ends of a last will, and does vary, more than 'onesixth of an inchas an extreme, with all possible minor graauations below such extremevariation. These'variations cannot be correctly provided for in the feedby a rack and pinion ofany pitch. where theradjnstment is one of toothby tooth. In the present construction, the automatic adjustment for lenhv of last is not governed by the pitch 0 the rack teeth, nor the timeof turning' at the heel or toe by the pitch diameter of the drivinginion. 'In the present machine when the eel or toe of the last arrivesat the oint where-it is desired to turn the same, e action of the sideguides assists in disconnecting the pinion from the rack with which itmay at that time be engaged, and the jack is locked or held fixed withreference to the center of the inion where it is held until the .turn ismad and thereafter the opposite rack engages with the pinthem' in. thedesired ion to again feed the shoe to bring the oppositeside under theaction of the machine.

The mechanism for swinging the jack as the toe or heel of the last isreached is as follows: Fitted in'dovetail hearings in the under sides ofblocks 16 and 18 (see Fig. 11) are slides 56, in which are formedsuitable bearings 57, in which are mounted the pins 58, which arepressed outwardly or in a direction to engage with the pinion 40 by thesprings 59. The outer ends of these spring pins 58 are flattened toenter the spaces between the teeth of the pinion 40 and said pins arearranged to project from the bearings more than the len h of a tooth ofsaid pinion. The inner on s of the slides 56 are formed into thin flatbars or arms and project far enough in advance of the face of thebearings 57 to.allow the notch 60 in their ends to enga e a pin 61 fixedupon and extending from t e end of shaft 41 and concentric with the axisof said shaft, when the flattened end of one pin 58 is engaged with theteeth of the pinion 40, \see Fig. 10) and when the notch 60 engages thepin 61, the ack is locked to the pinion, and said pinion is then disengaed from the rack with which it has been mes ing, and the jack instead ofhaving a longitudinal movement imparted to it by the pinion and rack,partakes of the rotary movement of said pinion moving the end of thejack in a curveu line with the shaft 41 as a center, and the surfacespeed of the end of the last past the lasting devices depends upon thedistance of the heel or toe'from this center. The adjustment for styleof heel or toe can be made by moving the slides'56 longitudinally in theblocks 16 and 18 and securing osition by the set screws 62 see Fig. 11.f the end of the toe of the last, when the jack and pinion are lockedtogether, is located in line with the pitch line of the pinion 40, itsspeed past the devices which secure the edge of the upper will be thesame as that which the sides of the last have been moved, and thestitches at the ends of the lasted upper would be too far apart if thetoe. of the shoe be a small one. If the end of the toe of the last whenthe jack and pinion are locked together, be

located directly in line with the pin 61, it

and locks the before describe and a fart or movement of the pinion andjack combined with the press anism the center of pin 58, which-willcause the sides and ends to move faster than the cornets of the lasts'Asthe'side guides meet the round end of the, or heel and the last turnsagainst said guides, tomeet the inclination one of the pins 58 eitherstrikes upon the point of'a tooth of-the pinion 49, or enters a spacebetween two teeth of said pinion. If it strikes the oint of a tooth thetgprinfi 59 yields, unti a space is presen w en said pin 58 enters saidspace inion and. 'ack together as sure of the side guides acts todisengage the pinion from the rack with which it was in mesh and thenotch '60 en ages with the pin 61, when the end of the ast moves aroundas described. When the pressure of the side guides is brought to bearupon the opposite side of the end of the last, y reverse movements thepinion engages with the other rack and the last moves endwise to againbring each portion of the upper along the sides in position to be actedupon. During the entire movement of the ack the side guidespress againstthe upper on the last or on the clamps 19 and 20 at the heel and toe andkeep the pinion 40 engaged with one of the side racks 39 or wit one ofthe end turning devices, and these side guides also act to osition thecurved sides of the last with r ation to the slitting and sewingdevices.

B the above described combination of mec anism four independent devices,the side racks and end turning devices are in turn connected to thepower 0 erated mechto feed and turn e jack and each side and end of thejack is operated by its special device without reference to the others,while such operation is taking place.

To enable the side ides to rform their functions without in ury tolt eupper, the base of the jack and its supporting table have been sciallyconstructed, the supporting table 8 beingof considerable size, andribbed or braced for the purpose of rigidity and strength. 'The laborand strain of jacking is brought as much as possibleupon the screws 27,and inspection of the drawings will show that the base of the jack whenthe top late 14 is in osition, forms a hollow gir er which is hght andat the same time so rigid that flex'ure under such strain as may bebrought upon it during the lastin operation is almost impossible.

11 order to rovide for a free movement of the jack, t bottom face of thebase plate 12 and the top face of the table 8 are fitted to each otheras are the contacti surfaces of surface plates, of which it is we knownthat one of a very heavy pair of plates can be moved upon the other witha slight exertion of power, or if desired any able lubricant ma be emloyed between the jack plate 12 an the ta 1e 8 to. assist the easymovement of the jack, so that said jack' maybe moved readily .bythe'teed mechaand controlled by the side e'belt devices, as hereinbeforedescribed.

ulley A is connected to and disconnected rom the main shaft 5, manuallyor automatically as required by a train of mechanism comprising theshort shaft 63 mounted to turn in the cars 64 on the jack supportingtable 8. To one end of shaft 63 is fixed the shi per lever 65 and to.its opposite end the bel crank lever 66 and 67, the lower arm 66 ofwhich is inclined or provided with a cam face 66' arranged to engage.the double ended lever 68 and move the same from the position of thedotted lines Fig. 4 to the position of the full lines Fig.. 4, when theshipper lever 65 is moved to the position Fig. 1, or fully depressed.
